Hello, Thank you for asking at HCM. I went through your history and would like to make suggestions for your daughter as follows: 1. Common cause of snoring at this age is nose obstruction or obstruction somewhere in upper respiratory airway. 2.If she has repeated cough-colds, I would think of nose obstruction due to long standing allergic rhinitis and would prescribe him combination of levocetirizine and montelukast. In that case, I would also suggest allergy testing. 3. However, if she does not have repeated cough-colds, I would first suggest her to get examined by an ENT specialist who will examine her nose passages from inside (if necessary) and would identify the cause of snoring. 4. As her sleep is disturbed due to snoring, it is suggestive of obstructive sleep apnea and hence should be evaluated to identify the cause. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at HCM. Wish your daughter the best of the health ahead. Thank you & Regards.
